San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Why Do Pest Control Companies Do A Bad Job With Poisons When It Comes To Removing Rats?
Aside from not being able to get all the rats, there are many reasons why we don't feel satisfied when a pest control company uses poison in removing rats. At times, things end up worse than they were, with other issues coming up. Using poison on rats brings about more jobs for you as a homeowner.
Think of the poisoned rats that die in the open - what happened to them? The poisons used by pest control companies lead to massive internal bleeding. The affected rodents often end up bleeding out and dying anywhere the poison takes full effect. Imagine getting rid of the rat, and later having to deal with a bloody rat lying on your kitchen counter or your carpet?
This makes you feel like the pest control company has done an incomplete job. You will be forced to put on your gloves, grab a collection tool, and a plastic bag to collect the dead rats.
Aside from that, there might be some blood splotches to clean up. This needs to be done properly, as they pose a health risk to the household. After going through all this, you are faced with the problem of how to safely get rid of the bag - having a dead and decaying rat in your dumpster may bring other kinds of pests. You end the rat infestation with poison only to start a different problem with different pests.
Aside from the stress that comes with cleaning up after a dead rat, what happens if the rat does not eat the pest control company's poison? They can't force the rats to eat it.
When the rats do not eat these poisons, it can harm anything else that comes in contact with it including, children, pets, and other wildlife creatures.
Using rat poison as a method to remove rats leaves you wondering, is such a precarious pest control method worth it?
